在分子构型相似的偶极性非质子溶剂中,离子、偶极间作用是影响碱金属离子与二苯并-18-冠-6络合生成常数K_f的主要因素。本文提出了可以从某一溶剂中的已知K_f值来计算另一溶剂中K_f值的方法。算得的K_f值与文献中的实验值相符合。
Among the dipolar aprotic solvents with similar molecular configuration, the interaction between ions and dipoles is the main factor that affects the complexation of alkali metal ions with dibenzo-18-crown-6 to form a constant K_f. This paper presents a method for calculating the K_f value of another solvent from a known K_f value in a certain solvent. Calculated K_f value consistent with the experimental value in the literature.
